1 Claim.

This invention relates to a cooler and conditioner for air and it aims to provide a novel apparatus wherein an absorbent element is maintained saturated with water, air is drawn through the saturated element through the action of a 5 fan, creating an unusual amount of evaporation,

the latter causing the air to cool and also washing it as it is drawn through the mist and saturated means, thereby becoming conditioned.

It is also aimed to provide such a structure as l may be used in connection with a room or inolosure, mounted in a window opening or in any other desired position.

The more specific objects and advantages will become apparent from a consideration of the l description following taken in connection with accompanying drawing illustrating an operative embodiment.

In said drawing:

Figure 1 is a side elevation of the invention;

Figure 2 is a plan View of the invention;

Figure 3 is a vertical sectional view taken on the line 3-3 of Figure 2; and

Figure 4 is a detail horizontal sectional View taken on the line 4-4 of Figure 3.

Referring specifically to the drawing wherein like reference characters designate like or similar parts, represents a casing of any desired shape to be used at any preferred location as in a window. Such casing 30 may be metallic, havfao ing an interior partition wall 3l equipped with a discharge opening therethrough surrounded by a continuous flange 23' within which a fan 25' is located, driven for instance by an electric motor 26 from any suitable source of current.

:1.3 The interior wall of this casing has a discharge opening at 32, in communication with the room or space into which the conditioned air is to be discharged. A pan 33 extends rearwardly beyond the partition 3|, at the base of the casing .gg A3l] and an absorbent web I4 of burlap, other cloth or the like, adapted to be saturated with water and maintained saturated, is angularly dis- (o1. zei- 106) posed, beingarcuate in horizontal section, and fastened in any suitable manner to the shelf 33 and to a rearward extension 34 of the top wall of the casing and supported by equidistantly spaced rods 34a extending from pan or extension 33 to extension 34 and supported by equidistantly spaced rods 34a. extending from pan or extension 33 to extension 34.

Water from any suitable source is supplied through a pipe 35, leading to an arcuate header 36 having discharge nozzles 31 connected thereto and arranged to discharge the water in a horizontal direction. The excess of water is caught by the pan 33 and it drains therefrom through a pipe 38. water through the pipe is continuous and may The supply of be regulated or cut-off through operation of a valve 39 in said pipe.

As a result of the construction described, the water continuously discharges from the nozzles 31 onto the web I4', being regulated or cut-off when desired by the valve 39. The apparatus is usually located in a window so that air passes from the exterior of the room through the moistened web I4', being cooled and Washed and accordingly conditioned, and discharges through opening 32 into the room.

I claim as my invention:

A device of the class described having a casing provided with a discharge opening, said casing having a rear wall provided with a discharge opening, a semi-circular rearward extension on 4the casing adjacent the base thereof forming a pan, a rearward extension on the top wall of the casing, a web of porous material disposed angularly about the entire periphery of said extensions, spaced supporting means for the web extending between said extensions, means to supply water to the web adjacent the top thereof,

a drain for the pan, and a fan operable to draw air through the web said openings.

and discharge it through RICHARD C. SLATER.
